This ethos extends to their global partnerships, including collaborations with ISO- and GMP-certified pharmaceutical labs and leading universities in the U.S. and Spain.

Sour Diesel Auto is the autoflowering version of the highly-acclaimed Californian delicacy known simply as Sour Diesel. She maintains all of the exceptional quality of her feminised namesake, delivering banging flavour and a heavy effect, only in shorter time.

This Sativa/Indica/Ruderalis strain was born from a cross between Sour Diesel #2 and Ruderalis, adding tremendous auto-speed to truly elite genetics. Her limited auto height of up to 1.5m makes her an ideal Sativa for cultivating indoors or in cities.

Sour Diesel Auto’s buds are beautifully dense, elongated and remarkably resinous.

Fans of Diesel strains will delight in her scent of citrus and exotic wood, as well as her flavour of Diesel and sour fruit.

Sour Diesel Auto delivers a clear Sativa effect – one that’s exceptionally euphoric, long-lasting and potent.

Sour Diesel Auto marijuana plants grow easily and quickly, both indoors and outdoors, and require little space, relative to their Sativa-dominance. Light but frequent watering and a 30% coco coir substrate are recommended to keep soil aerated and maximise nutrient uptake, translating into better-quality yields.
